Lenz’s law /ˈlɛnts/ is a common way of understanding how electromagnetic circuits obey Newton’s third law and the conservation of energy. ... more
The magnetic field generated by the electric current, around a straight wire, is related to the electric current and the distance “r” from the ... more
In physics, the gyromagnetic ratio (also sometimes known as the magnetogyric ratio in other disciplines) of a particle or system is the ratio of its ... more
In astrodynamics, the vis viva equation, also referred to as orbital energy conservation equation, is one of the fundamental equations that govern the ... more
Generated at the center of a circular wire by the electric current, related to the electric current and the distance from the wire to center of the circle.
